[jira] [Created] (YARN-11344) Double check locking in Configuration
Bence Kosztolnik created YARN-11344:
---------------------------------------
Summary: Double check locking in Configuration
Key: YARN-11344
URL: https://issues.apache.org/jira/browse/YARN-11344
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Reporter: Bence Kosztolnik
Currently the
{code:java}
org.apache.hadoop.conf.Configuration{code}
class use synchronised methods in many cases where double check locking would be enough, for example at case of *getProps()* and {*}getOverlay(){*}.
The class should be refactored to remove the unnecessary locking points.
